Each window is a range, not a single day. Earlier in the range buys you a longer season; later in it buys you a safer one.

Six weeks before your last frost, under cover or on a windowsill.

Sow for autumn

Counting back 74 days from your first frost so the crop matures in time.

Why these dates

Sow every ten days from six weeks before last frost. Pause through midsummer, then resume for an autumn crop - late sowings are often the best of the year.

Tolerates -3C and a light frost actually sweetens the leaf. Seed germinates poorly above 25C, which is the more common problem.

Seed packets and extension guides express timing as weeks either side of the last spring frost, because that is the only reference point that travels. Lettuce are timed from 6 weeks before that frost for an indoor start, with planting out 2 weeks before it, and this page simply resolves those offsets against the frost date computed for The Bronx.

The median frost-free season here is 203 days, against 45 to 60 days to maturity for this crop counted from sowing. That margin is what decides whether a late sowing is worth attempting.
